Shapo tools is a well known name for manufacturing metering proportioning and dosing pumps, offers a wide range pumps with hydraulically operated diaphragm type liquids ends which are ideal for use in case of hazardous toxic, radio active, expensive or poisonous liquid where no product leakage is acceptable. The company supplies metering pumps in various sub standard, double diaphragm, sandwich diaphragm and open dish sandwich diaphragm types applicable for different jobs. For very severe duty conditions or handling slurry, double diaphragm, sandwich diaphragm, open type sandwich diaphragm pumps are applicable. The company provides these hydraulically operated diaphram metering pumps with a rupture detection system for detecting diaphragm failure to prevent contamination of metered fluid. In standard type, the diaphragm constructed of teflon comes hydraulically actuated only to function as a partition. These hydraulically operated diaphragm pumps have a longer life with minimized leakage of process fluid as it is hermetically sealed. The diaphragm remains always in hydraulic balance with the liquid being pumped on one side and process fluid on the opposite side thus has a long life. The system is safe guarded by built in relief vacuum valve on the hydraulic side with which a very high pumping pressures can be attained.
